DEVICE FOR UNLOADING CARS.

SPECIFICATION forming part of Letters Patent No. 400,049, dated March 26, 1889.

Application filed June 18, 1888. Serial No. 277,401. (No model.)

To all whom it may concern.-

Be it known that I, JOHN L. BRYANT, a citizen of the United States, residing at Hillsdale, in the county of Hillsdale and State of Michigan, have invented certain new and useful Improvements in Devices for Unloading Oars upon Railway-'lracks, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to new and useful improvements in a device for unloading cars upon railway-tracks; and the invention consists in the peculiar construction, arrangement, and operation of a tilting track, whereby a car or a number of cars placed thereon may be tilted to either side to dump the load, all as more fully hereinafter set forth, and then definitely pointed out in the claims.

In the drawings which accompany this specification, Figure 1 is a perspective view of the bed upon which a tilting track (not shown) is intended to be supported, showing the means for operating it. Fig. 2 is a cross-section through the line a: as, Fig. 1, showing also a tilting track on the bed and the device as in operation; and Fig. 3 is a side elevation with the tilting track as in normal position.

A is a stationary elevated railroadt.rack. B is a pivoted section thereof. 0 are trunn'ions supporting said pivoted section of track at its ends in suitable bearings, D, in the abutting ends of the stationary track or bed.

E is a shaft journaled in suitable bearings below the pivoted section of track longitudinally in the center thereof.

F are one or more pinions upon the shaft E.

G is a segmental gear secured to the under side of the pivoted track, one for each pinion F to mesh into.

H is a segmental semicircular flange or bearing concentric with the segmental gear G, secured to the under side of the pivoted track, and preferably formed integral with the segmental gear.

I is a roller or bearing on the shaft E, on which the segmental semicircular flange H rides to support the weight of the pivoted section of track.

J are side rollers for additional supports.

K is a crank or handle for rotating the shaft E either by the direct application of power or by means of intermediate gearing, as shown in the drawings.

L are movable props supporting the pivoted track normally in its horizontal posit-ion.

M are hinges securing the props to the bed.

N are springs to normally hold the props in vertical position.

0 are shafts journaled in proximity to the props and provided with arms P, impinging against the inner side of the props L.

Q are handles for rotating the shafts O.

In practice, the parts being arranged and constructed as described, the device is intended to operate as follows: The car to be unloaded is run upon the pivoted track and firmly secured thereto against accidental displacement, suitable devices being arranged for'that purposesuch as rods or chains R along the side of the car'as shown in the drawings. The operator, by actuating one of the handles Q, vibrates the props from one side of the pivoted track, whereby the car and track are free to be tilted to the side upon which the props are withdrawn. The tilting movement is effected by rotating the shaft E by means of the device shown.

There may be suitable stops provided in the actuating mechanism of the shaft E to arrest the tilting track when the proper angular position is obtained; or, as shown in the drawings, the buffers R may be provided alongside the tilting track, against which the car abuts at the desired inclination. I preferably support upon these buffers the inclined chutes in such relative position to the car that if the car tilts the material will run down the chutes. These chutes are preferably slidingly secured upon the buffers and prevented from accidental displacement by the counter-weights T, which project the chutes beyond the buffers, so as to form a yielding stop, against which the momentum of the car in tilting is checked until it strikes the buffer, so that a continuously tight joint is maintained between the car and the chute, while at the same time the righting of the car after the load is dumped is greatly facilitated. These chutes may be provided on one or both sides of the car, as desired, and the tilting may be carried out either to one side or the other. Suitable provision can easily be made for this kind of 5 \Vhat I claim as my invention is- 1. In a device for unloading ears upon railrozul-tracks, the combination of a section of track, pivota-lly secured at the end of a connectingtrack, and gearing for operating 10 and rollers for supporting the pivoted track mounted on the same shaft, substantially as described.

2. The combination, with a tilting track and its trunnions, of a semicircular flange and a 1 5 segmental gear connected thereto, asha'f t centrally arran ged hen eath the same, a gear-wheel meshing with said segmental gear, and a roller oinvhich the flange rests, both gear-wheel and roller being on the same shaft, substantially 20 as described.

3. The combination of the tilting track, two series of movable props beneath the track supporting the same on opposite sides, the shafts O and arms I, for moving simultaneously all of either set of said props, and the central. gear-connection for tilting the track in either direction, substantially as described.

4. The combinatiomwith the tilting section of track, of the stationarybu'lfer secured al on gside said track and the sliding counterweight ed chutes supported thereon, substantially as described.

In testimony whereof I af'fix my signature, in presence of two witn esses, this 26th dayo'l' May, 1988.
